Cluj-Napoca in August

May through September gives you the best weather, but each season has its charm. Spring arrives early — by April, the terraces are full and the city sheds its winter coat. Summer means festivals every weekend, including the massive Electric Castle in July. But it also means crowds and higher prices. September is perfect — warm days, cool evenings, and the students are back, which means the city buzzes with energy. October brings beautiful fall colors to Central Park and fewer tourists. Winter isn't terrible if you can handle some snow, plus you'll have the city mostly to yourself. The Christmas market in Unirii Square runs through December and into January. Just know that many outdoor attractions close or reduce hours from November to March.
